Woman killed by San Jose police is identified

SAN JOSE -- Police have publicly identified a 19-year-old woman who was shot and killed by an officer last week during a confrontation in which she claimed to have a gun but was actually carrying a black cordless drill.

According to San Jose police, Diana Showman, of San Jose, died Thursday morning from a single bullet fired by Officer Wakana Okuma following a sequence of events that started with Showman reportedly calling 911 and threatening her family with an Uzi, a kind of submachine gun.

Officers, including Okuma, who has crisis intervention training, responded to the call at the home at Blossom Hill Road and Playa del Rey in South San Jose.

After police called out to her, Showman emerged from the home with an object in each hand and at some point dropped one, authorities said.

She continued advancing toward the officers with what turned out to be a cordless drill painted black, though officers would not find that out until afterward.

Police and witnesses -- some of whom captured the incident on cellphone video -- said ﻿when Showman got within about 15 feet of Okuma, the officer opened fire.

Showman was hit in the chest. She was rushed to the hospital, where she died from her injuries.

Okuma, who was the only officer who fired, has been placed on administrative leave pending an investigation monitored by the District Attorney's Office, which is routine in officer-involved shootings.

Police sources and family members said Showman's bipolar disorder may have factored into the conflict, but the full circumstances remain under investigation.
